My first working SSTC. Based on Steve Conner's PLL driver, runs from half-wave rectified mains, secondary fres 500kHz, secondary height = 20cm. Needs primary tuning, but I consider it complete for the time being.

My first SSTC, it's basically Steve's Micro SSTC, but I replace the TC4420 with UCC37322 and add an interrupter. The interrupter is the same as the one used in Steve's Class-E.
It runs from a 30VDC, secondary frequency is unknown yet.(taken from my old SGTC) Topload is a stainless steel sphere(2inches in radius). With interrupter, streamers reach 4cm while IRFP460 staying cold.
